Post-COVID-19: minimally important difference survey

WHO is seeking to refine our understanding of minimally important differences (MID) for Post COVID-19 Conditions. Minimally important differences are the smallest changes in outcomes or measurements that are considered significant enough by patients to indicate a noticeable improvement or worsening of a condition.
